Abstract (en)
[origin: US5125336A] The device has a transfer cylinder (2) with a drum (4) which is adjustable in the circumferential direction relative to its shaft (3) and which carries sheet grippers (8) with a front stop (8a) for the sheets (B). The diameter of the transfer drum (2) is equal to 1/N of the diameter of the plate cylinder which carries N printing plates. The shaft (3) of the transfer cylinder (2) rotates at a constant speed and executes N revolutions when the plate cylinder is executing one revolution. By means of a controllable setting device, the drum (4) is so displaced relative to the shaft (3) during each revolution that the front stop (8a), when its transfer position in which a sheet is transferred to the impression cylinder (D) is passed, assumes a position by which the exact register of this sheet in relation to the position of the printing plate printing it on the plate cylinder is set. This guarantees that the width of the front margin between the sheet front edge and print start is of the same size on all the printed sheets, without the need to adjust the printing plates exactly on the plate cylinder in a time-consuming way.
